Description

Technical Field

[0001] This application relates to the field of debris flow barrier dams, specifically a debris flow barrier facility, and more particularly to a composite barrier dam composed of anchor cables, passive netting, and gabion retaining walls. Background Technology

[0002] With rapid economic development, the scale of highway construction and development has grown exponentially, leading to an increasing number of roads and bridges traversing mountain valleys, highlighting the growing importance of preventing debris flows. Reinforced concrete retaining dams offer advantages such as good retaining effect, long service life, and low maintenance costs. However, reinforced concrete retaining dams also have high construction costs, long construction time, and high repair costs after damage. Therefore, a large number of low-cost, simple-to-construct retaining dams are needed along mountain road and bridge projects. Utility Model Content

[0003] The purpose of this invention is to provide a composite retaining dam composed of anchor cables, passive netting, and gabion retaining walls. This addresses the problems of high construction costs, long construction times, and high repair costs associated with reinforced concrete retaining dams.

[0004] The composite retaining dam consisting of anchor cable-passive net-gabion retaining wall includes: gabion retaining wall 1 (wire mesh 1-2), ground anchor 2, steel bar 3, corrugated pipe 4, cross-shaped anchor cable 5, passive net 6 (pressure relief ring 6-1, ring buckle 6-2, 6-3 steel cable), concrete wall 7, and concrete slope 8.

[0005] The aforementioned composite retaining dam, consisting of anchor cables, passive netting, and gabion retaining walls, includes the main gabion retaining wall 1, with crushed stones neatly arranged within wire mesh 1-2. Ground anchors 2 should be installed first at the beginning of the project. One end of a reinforcing bar 3 is fixed to the ground anchor 2, and the other end is fixed to the concrete wall 7 by a cross-shaped anchor cable 5. The reinforcing bar 3 is wrapped with corrugated pipe 4. The passive netting 6 is placed behind the concrete wall 7 and fixed with steel cables 6-3. The steel cables 6-3 are equipped with pressure-reducing rings to prevent the cables from breaking under impact.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] (1) The main body of the structure is a modular structure, which can be quickly assembled during construction. Compared with the current construction technology, it shortens the construction time and improves the process quality and construction efficiency.

[0008] (2) Since the main body of the barrier dam is composed of gabion retaining walls, it is convenient and quick to maintain and replace the retaining walls when they are damaged.

[0009] (3) I-beams are easy to transport. The addition of ribs inside the beam increases the load-bearing capacity, and the I-beams can be quickly replaced when they are damaged.

[0010] (4) Gabion retaining walls have lower construction costs and shorter construction time, and can provide stable retaining capacity under harsh conditions.

[0011] This utility model is simple to install, convenient to use, has a reliable connection method, and reasonable stress distribution. The materials used in this application are common and readily available, and can be widely promoted and used. Attached Figure Description

[0020] In the diagram: Gabion retaining wall 1, wire mesh 1-2, ground anchor 2, steel bar 3, corrugated pipe 4, cross-shaped anchor cable 5, passive net 6 (pressure relief ring 6-1, ring buckle 6-2, 6-3 steel cable), concrete wall 7. Detailed Implementation

[0021] To make the technical means, features, purpose and effects of this utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, this utility model provides a design scheme including a gabion retaining wall 1, wire mesh 1-2, ground anchor 2, steel bar 3, corrugated pipe 4, cross-shaped anchor cable 5, passive net 6 (pressure reducing ring 6-1, ring buckle 6-2, 6-3 steel cable), concrete wall 7, and concrete slope 8.

[0023] In this implementation case, a relatively flat area should be found in the debris flow gully. After fixing one end of the reinforcing bar 3 to the ground anchor 2, the ground anchor 2 is placed into the pre-dug deep hole and grouting is performed. After the concrete has solidified, it is completely buried. The gabion retaining wall 1 is arranged in a stepped pattern, narrow at the bottom and wide at the top. During the arrangement, the reinforcing bar 3 is passed through the gabion retaining wall. In the area where the cross-shaped anchor cable 5 needs to be installed, the steps created by the gabion retaining wall 1 are poured with concrete to form a flat concrete slope 8. After the concrete has solidified, the passive net 6 is laid on the entire back slope of the retaining dam and fixed with steel cable 6-3 with pressure-reducing ring 6-1. The two ends of the steel cable 6-3 are fixed to the slopes on both sides of the gully with ground anchor 2. The ground anchor 2 is grouted with concrete. Finally, the reinforcing bar is prestressed with jacks and locked with cross-shaped anchor cable 5.

[0024] The technical solutions provided in this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the methods and core ideas of this application. For those skilled in the art, modifications and improvements can be made to this application, and these modifications and improvements are also included within the scope of protection of the claims of this application.
